Study on the Thermoconductivity Properties and Mechanism of Boron-Containing Slag
. In the range of 1200°C to 1500°C, the transient hot-wire method was applied to measure the thermoconductivity of boron-containing slag, and the characteristics relationship of thermoconductivity with temperature was obtained. The thermoconductivity decreased rapidly with the elevation of temperature in the concerned temperature zone. The effect of thermoconductivity from compositions was obtained in the concerned temperature zone. The thermoconductivity increased with the increase of component of SiO2 and MgO. This is in favor of realization of quick cooling and increasing efficiencies of extraction of boron. This study not only provides an important properties parameter for the integrated utilization of boron-containing slag and helps to understand the conductivity mechanism of boron-containing slag, but also has a reference significance and practical value about the development of heat conduction theory in silicate system.
